Today, Amazon Elastic Container Service (ECS) is announcing availability of ECS-optimized Amazon Linux 2023 (AL2023) AMIs and group managed service accounts (gMSA) on ECS Linux containers through credentials-fetcher integration. gMSA is a managed account that provides automatic password management, service principal name (SPN) management, and the ability to delegate management to administrators over multiple servers or instances. This integration allows applications hosted on Amazon ECS Linux containers to easily authenticate with Microsoft Active Directory (AD) to access network shared resources. This integration enables customers to continue using AD as well as get the cost, reliability, and scalability benefits of Amazon Linux on ECS.
